The Factory Cat model TR's design was built from the success of our Model 34 walk behind sweeper. The TR's side brooms sweep up dirt in the corners while a huge tubular sweeping broom under the machine sweeps up the dirt and debris from the floor and packs it into the steel hopper. Meanwhile, the second stage vacuums up the dust and traps it in a polypropylene felt baghouse filter. Factory Cat's Industrial floor sweepers can pick up whole bags of cement at a time without leaving a trace of dust behind.
